I am ok with however you choose to implement, 8 unidirectional or 4
bidirectional channels or whatever.

We just can't have protocol specific s/w modes in the controller drivers.

The best solution is to fix the SCU firmware. If that is _really_
impossible, I provided a solution (3 cells work around). If you have a
better idea please feel free to propose and implement that.

It will also help if you could share the user code of "scu-mode". If
there is no such code (and we know the driver doesn't respect the
"scu-mode" property) why do we even have that binding? Maybe drop it.

thnx.
